Resilient mobile meshed network with extended range

ABSTRACT

Various embodiments comprise systems, methods, architectures, mechanisms or apparatus configured to provide ad hoc, peer to peer communications among a plurality of wireless devices, wherein at least one wireless device is selected to further communicate with a wireless network to provide thereby backhaul services to other wireless devices, wherein the at least one wireless device providing backhaul services is dynamically selected in accordance with respective wireless network signal strength indicia.

FIELD OF THE DISCLOSURE

The present disclosure generally relates to wireless networking and, in particular, ad hoc mesh networking of wireless devices with dynamic selection of backhaul hosting wireless devices.

BACKGROUND

Mobile or cellular networks/systems using licensed spectrum (e.g., Third Generation (3G) Partnership Project (3GPP) networks, 3GPP2 networks, Long Term Evolution (LTE) networks, 5G networks and the like) and wireless local area networks/systems (WLANs) using unlicensed bands of spectrum (e.g., Wireless Fidelity (WiFi) access networks and the like operating at 2.4 GHz, 5 GHz and other spectral regions) are used for providing wireless services in a complementary manner to wireless/mobile devices.

Mobile/cellular networks generally provide macro cellular coverage outdoors and within those areas of buildings and other structures (e.g., tunnel) where mobile network signal of sufficient strength exists (i.e., signal penetrating the building at sufficient strength or signal boosted/distributed therein). Wireless local area networks generally serve enterprises, residences, public venues, and the like.

Device driven ad-hoc networks rely on a WiFi hotspot being created by a host device connected to a mobile network to provide a wireless access point (WAP) for use by other devices. In this situation the other devices use the WiFi connection to transfer data to and from the mobile network via the host device, which data traverses the entirety of the ad hoc network. Such data may comprise voice communications, streaming media, email, messaging and any other mobile service.

All data transferred to and from the mobile network by the host device consumes bandwidth allocated to the host device, such as bandwidth associated with a mobile network subscription associated with the host device. Direct communication between devices connected to the ad hoc network must also pass through the mobile network.

SUMMARY

Various deficiencies in the prior art are addressed by systems, methods, architectures, mechanisms or apparatus configured to provide ad hoc, peer to peer communications among a plurality of wireless devices, wherein at least one wireless device is selected to further communicate with a wireless network to provide thereby backhaul services to other wireless devices, wherein the at least one wireless device providing backhaul services is dynamically selected in accordance with respective wireless network signal strength indicia.

FIG. 1 depicts a high-level block diagram of a system benefiting from various embodiments. Specifically, the system 100 depicted in FIG. 1 comprises a plurality of wireless devices (e.g., mobile devices) denoted as 110-1, 110-2 and so on up to 110-9 (collectively wireless devices 110), a plurality of mobile network access devices 120 illustratively 4G/LTE 122 and 5G 124 access devices (e.g., base stations, eNodeBs and the like) and a service provider network 140, illustratively including 3G provider equipment (PE) 142-3, 4G PE 142-4 and/or 5G PE 142-5, as well as elements implementing network management, services and accounting functions such as a Mobility Management Entity (MME) 144, Policy and Charging Rules Function (PCRF) 145, Home Subscriber Server (HSS)/Authentication, Authorization and Accounting (AAA) server 146 and/or and various other provider equipment (not shown) suitable for implementing mobile network infrastructure such as discussed herein with respect to 3G, 4G, 5G and/or other mobile network types.

The wireless devices 110 are generally described herein as mobile phones including a mobile network interface configured to support mobile network communication with one or more radio access networks (RANs) such as 3G, 4G/LTE, 5G and/or other RANs providing mobile network services. The wireless devices 110 further include the wireless network interface configured to support wireless network communication between the various wireless/mobile devices to form thereby and ad hoc mesh network of wireless/mobile devices.

Thus, FIG. 1 depicts a plurality wireless devices 110 wherein each wireless device is connected to at least one other wireless device via respective wireless network interfaces to form thereby an ad hoc mesh network, and wherein one or more of the wireless devices is further connected to a mobile network to support thereby bearer channels communicating data between the various wireless devices of the ad hoc mesh network and respective source/destination devices communicating with the mobile network or networks connected thereto (e.g., access networks, core networks, other mobile networks and the like).

The ad hoc mesh network of the various embodiments is formed as wireless devices discover that other wireless devices are nearby and establish communications there between. The network 100 of FIG. 1 is depicted as comprising nine wireless devices 110 where each of the wireless devices 110 is coupled by the ad hoc mesh network to some but not all of the other wireless devices 110, and where some of the wireless devices 110 are coupled to the service provider network 140 via a mobile network access device 122-124.

Each wireless device 110 operates in a discovery mode to discover other proximate wireless devices 110 and establish communications with such devices via their respective wireless network interfaces in accordance with an ad hoc network protocol. In various embodiments, a common authentication key is used by each wireless device.

The various anchor and non-anchor wireless devices 110 utilize mobile services such as voice, data, streaming media and so on as supported via one or more wireless devices 110 operably coupled to the mobile network 140 as anchor devices.

Each wireless device 110 operates to monitor and share with other wireless devices 110 various anchor related criteria such as the type, performance and/or quality of its local (i.e., reachable or proximate) mobile network access devices 122/124 such that one or more anchor devices may be selected in accordance with a common selection criteria. As previous noted, the type of access device may comprise 3G, 4G/LTE, 5G and the like. Depending upon the mobile services required by non-anchor wireless devices 110, or the subscription plan or data/bandwidth utilization or other capabilities of an anchor wireless device 110, one type of access device 122/124 may be preferred over another type. Further, the signal quality of the mobile network access devices 122-124 is monitored, such as the signal strength, quality of service deliverable by the signal, bit error rate associated with the signal and/or other performance metrics.

Each wireless device receives type performance and/or qualitative information pertaining to the local mobile network access devices associated with the various other wireless devices such that each wireless device may independently make the same determination as to which one or more of the wireless devices forming the ad hoc network is to be utilized as an anchor device.

Those wireless devices determined to be anchor devices enter an anchor device operating mode wherein they provide backhaul data services in support of the mobile services utilized by the various wireless devices forming the ad hoc mesh network.

As the distance between wireless devices increases or decreases as the devices move, the ability to maintain direct communication between the devices changes. As such, new wireless devices may discover and join the ad hoc networks, connected wireless devices may drop out of the ad hoc network and so on. Similarly, those wireless devices operating as an anchor devices may also experience increases or decreases in ability to maintain communication of sufficient quality with the mobile network. As such, new anchor devices may be selected as needed, existing anchor devices may revert to a non-anchor mode of operation (or drop from the ad hoc network altogether) and so on. Thus, the ad hoc mesh network is continually changing in terms of wireless devices forming the network as well as the anchor devices supplying backhaul services.

For example, referring to FIG. 1, wireless device 110-1 is depicted as communicating with a 4G access device 122-3, wireless device 110-9 is depicted as communicating with a 5G access device 122-2, and wireless device 110-5 is depicted as communicating with both a 4G access device 122-1 and a 5G access device 124-1. All of the access devices 122/124 communicate via backhaul channels to the service provider network 140 and, subsequently, other networks, servers, service providers and the like connected directly or indirectly thereto.

It will be appreciated by those skilled in the art that the wireless devices 110 may comprise any wireless device mobile or stationary, such as a computing device, tablet, routing device and the like.

The various embodiments advantageously enable direct communication between devices connected to the ad hoc mesh network, thereby avoiding the consumption of anchor mobile network bandwidth.

The various embodiments advantageously support dynamic addition/deletion of users/devices. Specifically, various embodiments each device connected to the ad hoc mesh network as provided with the same administrative privileges such that any of the devices may perform administrative tasks such as authenticating/admitting new devices to the ad hoc network, terminating or restricting access to the ad hoc network by some devices and so on.

FIG. 2 depicts a high-level block diagram of an exemplary wireless device suitable for use in the various embodiments. Specifically, the wireless device 200 of FIG. 2 is suitable for use in implementing the wireless devices 110 described above with respect to the system 100 of FIG. 1.

The wireless device 200 of FIG. 2 is depicted as including as including one or more processor(s) 210, a memory 220, a user interface 230, a mobile network interface/transceiver 241 and antenna 251, a wireless network interface/transceiver 242 and antenna 252, and an optional other interface/transceiver 243 and antenna 253.

These instructions that can be executed by processor(s) 210. Various types of instructions may be stored in memory 220. For instance, memory 220 may store instructions that control the operation of communication interfaces/transceivers 241-243, the operation of user interface 230 as well as the operation of other elements within the wireless device 200.

The user interface 230 facilitates the exchange of information with a user. The user interface 230 may comprise various user input and output devices, such as a keyboard, a display device, a touch screen display device, audio speakers and the like to enable user to enter information into the wireless device 200 as well as view information provided by the wireless device 200.

The optional other interface 243 and antenna 253 as depicted herein are configured to support communications with other wireless devices 200/110 via other communications means/protocols such as Bluetooth, ultra-wideband (UWB) and the like.

The memory 220, generally speaking, stores programs, data, tools and the like that are adapted for use in providing various functions as described herein with respect to the figures. For example, the memory 220 is depicted as storing instructions associated with a mesh connection a control module 222, a device and services control module 224, other programming 226 as well as data storage 228 (including storage for mesh network routing tables and related information, mobile network QoS tables and related information), which instructions cause the respective modules either individually or in combination to perform the various functions of the embodiments described herein. The memory 220 stores instructions controlling the transmission and reception of data via the various interfaces 241-243 in accordance with the appropriate communications protocols, data and control formats, timing requirements, packet structures and the like.

FIG. 3 depicts a method according to one embodiment. Specifically, FIG. 3 depicts a method 300 suitable for use by each of the wireless devices 200/110 described above with respect to FIGS. 1-2.

At step 310, each wireless device 200/110 enters a discovery mode wherein the wireless device discovers proximate wireless devices and establishes a connection thereto using the wireless network radio or other radio. Illustrative embodiments of the discovery mode 310 are described in more detail below with respect to FIG. 4 (existing MM devices) and FIG. 5 (candidate MM devices).

At step 320, each MM wireless device 200/110 examines various criteria associated with an ability to perform hosting/anchor functions, such as the type and QoS of its respective local mobile network connections (i.e., local mobile network access points such as for 3G, 4G/LTE, 5G etc.), subscription information such as amount of mobile network data allowed, utilization of allowed data, allowed data rate, mobile network subscription tier QoS and the like, and transmits this information toward each of the other MM wireless devices 200/110 forming the ad hoc mesh network. This information may be stored in, illustratively, MM QoS tables and/or other locations within the MM.

At step 330, each MM wireless device 200/110 uses the same criteria to evaluate the local and received mobile network type/QoS information to select one or more anchor devices to support the other ad hoc mesh network wireless devices. A MM wireless device 200/110 selected as an anchor device enters an anchor mode of operation wherein bearer traffic associated with the various nodes of the ad hoc mesh network is supported/transported via the mobile network interfaces of the anchor device.

In some embodiments, the wireless device exhibiting the highest mobile network signal strength is selected as the anchor device. In some embodiments, the number of anchor devices selected is proportionate to the number of nodes within the ad hoc mesh network. In some embodiments, the number of anchor devices is selected such that each wireless device is within a predefined number of hops (e.g., two, three, five or some other number) of an anchor. In some embodiments, an anchor device is not selected if subscription or data plan associated with the anchor device is utilized beyond a threshold level (e.g., 50%, 80%, 90% or some other amount). In some embodiments, wireless devices associated with 5G networks are preferentially selected as anchors over wireless devices associated with other network types. In some embodiments, provider information relating to congestion or other network conditions is included in the evaluation performed by each wireless device and determining one or more anchor devices. In some embodiments, the ad hoc mesh network is divided into a plurality of areas or zones where each of the areas or zones is served via a respective one or more anchors.

At step 340, steps 310-330 are repeated in response to one or several criteria, such as periodically (e.g., elapsed countdown timer), a newly available mobile network or type of mobile network as indicated by one or more wireless devices, degradation of mobile network QoS of an existing anchor, assertion of a very high mobile network QoS by an existing non-anchor, indication of excessive data consumption or data utilization is indicated by an existing anchor and/or other criteria. Thus, various embodiments provide dynamic adaptation of backhaul links to the ad hoc mesh network to balance anchor loading, to utilize lower cost mobile network services, to provide redundancy, to provide resiliency and to otherwise ensure that the mobile services utilized by the various wireless devices within the ad hoc mesh network are maintained an appropriate quality of service level.

FIG. 4 depicts a discovery method suitable for use by a mesh network member (MM). Generally speaking, the method 400 of FIG. 4 may be used by existing MM wireless devices to discover nearby MM wireless devices such that routing tables associated with the ad-hoc mesh network (AHN) may be responsively updated, and to discover nearby candidate mesh network member (CMM) wireless devices for possible admission/authentication into the AHN.

At step 410, the MM transmits an Ad-Hoc network access invitation message including the identification number (AHN-ID) of the Ad-Hoc network. Referring to box 415, the invitation may be transmitted periodically (e.g., every 100 ms, every 500 ms, every second etc.) or in response to a received probe such as may be transmitted by a nearby wireless device that is a member of the Ad-Hoc network already (e.g., and moved into RF range of the MM) or a nearby wireless device that is a candidate for mesh network membership (CMM). The Ad-Hoc network access invitation message may be transmitted at a predefined power level (e.g., −3 dB of max power for the spectral region), at a power level based on a number of anchors used within the Ad-Hoc network, at a power level based upon the distance to an other anchor or some other criteria.

At step 420, the MM receives an Ad-Hoc network access request from a CMM, including a private mesh authorization key (PMAK) and any prior AHN connection information, where the PMAK is necessary for authentication to, and communication within, the AHN.

At step 430, if the CMM that transmitted the Ad-Hoc network access request is determined to be a prior MM of the Ad-Hoc network (optionally, of a related Ad-Hoc network), then the CMM is admitted to the AHN as a MM. This determination is based upon the prior AHN connection information received from the CMM, such the last few (e.g., 3-5) PMAKs used by the CMM. Specifically, since the PMAK of the AHN may be changed from time to time by any of the anchor MMs, the CMM may have been part of the AHN but disconnected from the AHN prior to a PMAK change such that the CMM is a prior MM and should be readmitted to the AHN. If the CMM is not a prior MM of the AHN, then the MM invokes an authentication process such as by a token/key exchange or other technique. In one embodiment, the MM generates a personal ID (PIN) for local display (e.g., the screen of a mobile phone if the MM is a mobile phone) such that the PIN may be entered into the CMM (e.g., via the user interface of the CMM). If the CMM provides the PIN to the MM then the MM admits the CMM to the AHN.

At step 440, if the CMM is admitted to the AHN as a MM, then the newly admitted MM is provided with routing table and related information to ensure that packets are routed properly within the AHN by the new MM. Further, the newly admitted MM also operates to discover other MM wireless devices for routing within the AHN, and to discover CMM wireless devices for potential admission to the AHN. Further, the newly admitted MM operates to become an anchor MM if appropriate. The general operating modes of the MM are described above with respect to FIGS. 2-3.

FIG. 5 depicts a discovery method suitable for use by a candidate mesh network member (CMM). Generally speaking, the method 500 of FIG. 5 may be used by non-mesh network members (e.g., CMMs) which may have MN subscriptions that include AHN membership/services.

At step 510, a CMM (e.g., a newly local or prior MM) receives an AHN access invitation request, either passively or in response to a probe transmitted by the CMM.

At step 520, the CMM interacts with the mobile network (MN) provider equipment (PE) management elements (e.g., PCRF 145 or similar) to determine is the MN subscription of the CMM includes an authorization for connection with the AHN. If so, then the MN PE provides the CMM with the PMAK of the AHN.

At step 530, the CMM transmits an AHN access request, including the received PMAK and any prior AHN connection information such as stored PMAKs from prior AHN membership.

At step 540, if the CMM is a prior MM for the AHN, then the MM interacting with the CMM will admit the CMM to the AHN as a MM. If the CMM is not a prior MM for the AHN, then the CMM waits for the MM interacting with the CMM to invoke an authentication process such as described above with respect to step 430 of the method 400 of FIG. 4 (e.g., the CMM receives user input indicative of a PIN generated by the MM and transmits the PIN to the MM, whereupon the MM admits the CMM to the AHN).

At step 550, the newly admitted MM is configured to operate in accordance with the AHN; namely, discovering proximate MM and CMM devices for potential admission to the AHN, updating routing tables in accordance with dynamic changes to the AHN and routing packets/traffic accordingly, updating MN QoS tables and the like in accordance with MN monitoring, and selecting new anchor MMs in response, such as entering an anchor mode if such mode is appropriate.

The above-described embodiments contemplate that an ad hoc network member such as an anchor member will receive ad-hoc network access requests from wireless devices and responsively establish ad hoc communications with requesting wireless devices having a current private mesh authorization key (PMAK) associated with the ad hoc network.

In various embodiments, where a requesting wireless device does not have the current PMAK, the anchor member will wait for an invoked authentication to the mobile network for requesting wireless devices (e.g., the requesting device interacts with the mobile network or other authentication authority to receive the information it needs, such as the current and/or past PMAKs and/or other information).

In various embodiments, where a requesting wireless device does not have the current PMAK, the anchor member a PIN may be generated by the anchor member or some other authorized entity such that the PIN may be transmitted to the anchor member by the requesting wireless device, whereupon the anchor may establish ad hoc communications with a requesting wireless devices.

In various embodiments, the routing tables cause anchor devices to route intra-ad-hoc-network bearer traffic within the ad-hoc network where the bearer traffic has a destination address associated with an ad hoc network member. In this manner, such traffic is not routed unnecessarily to (and received back from) the mobile network.

In various embodiments, the routing tables are updated each time an anchor member establishes (or loses/terminates) communications with a wireless device. Such routing tables are transmitted to other members of the ad hoc network such that the routing tables are kept substantially accurate.
